We know for newton's 2nd law of motion that the force on an object is equal to the mass of the object times the acceleration of that object. a 9kg bowling ball was thrown with a force of 5 n. what was it's acceleration? be sure to show how you solved the problem, not just the answer.

One day, after pulling down your window shade, you notice that sunlight is passing through a pinhole in the shade and making a small patch of light on the far wall. you see that the patch of light seems to be a circular diffraction pattern. it appears that the central maximum is about 1 cm across and you estimate that the distance from the window shade to the wall is about 3 m. what is (a) the average wavelength of sunlight? (b) the diameter of the pinhole?
